Abstract
The concerted applications of a variety of one‐ and two‐dimensional NMR techniques (COSY, NOESY, HETCOR, COLOC, etc.) to the structural elucidation of the natural 3,4‐bis[(3,4‐dimethoxyphenyl)methyl]dihydro‐(3__R__‐trans)‐2(3__H__)‐furanone, isolated from Oenanthe aquatica fruits, in CDCl~3~ solution are reported. The magnitude of the ^1^H,^1^H coupling constants obtained from the simulated spectrum together with a series of homonuclear NOE difference spectra were used to determine the full stereochemistry of the system.
